1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire and the wheel assembly. Refer to Tire and Wheel Removal and Installation.
3. Locate the leaking areas by inflating the tire to 275 kPa (40 psi) and dipping the tire and the wheel assembly into a water bath.
4. Mark the leak areas and remove the tire from the wheel. Refer to Tire Mounting and Dismounting.
5. Scuff the inside of the rim surface at the leak area with 80 number grit sandpaper. Clean the area with general purpose cleaner such as 3M P/N 08984 or the equivalent.
6. Apply a 3 mm (1/8 in) thick layer of adhesive/sealant P/N 1052366 or the equivalent to the leak area and allow 6 hours of drying time.
7. Mount the tire on the wheel. Pressurize the tire to 275 kPa (40 psi) and inspect for leaks. Refer to Tire Mounting and Dismounting.

Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury.

8. Adjust the tire pressure in order to meet specifications.
9. Balance the tire and the wheel assembly.
10. Install the tire and the wheel assembly. Refer to Tire and Wheel Removal and Installation.
